Choosing the Best Battery Backup Solution
Understanding Backup Battery Systems
Choosing the right battery system starts with understanding your specific needs and situation. Not all systems work the same way, so it’s important to find the one that fits your goals, whether you have or plan to install solar, how reliable your current power is, and how much backup power you might need.
System Options Overview
AC Coupled Battery System
- Best For: Customers wanting backup power without solar, or those with an existing solar system who want to add battery backup.
- Recommended Product: FranklinWH Battery
Solar and Battery Backup Hybrid System
- Best For: Customers who want solar and battery storage connected to the grid, aiming for energy independence while still relying on grid power as backup.
- Recommended Products: Enphase 5P Battery
Off-Grid Solar and Battery System
- Best For: Customers looking to go fully off-grid or those with limited grid reliability, needing a self-sustaining power solution.
- Recommended Products: SolArk Inverter with Discover Batteries

Asking the right questions
“What’s your primary goal with a battery system?”
- Backup Power: If you are primarily concerned with backup power for outages, an AC Coupled battery or hybrid solar-battery system may be best.
- Energy Independence: If you are aiming for total independence, we recommend a hybrid system or off-grid solution.
“Do you currently have a solar system, or are you planning to install one?”
- No Solar: If you want battery backup only, go with an AC Coupled battery.
- Existing or Planned Solar: Consider a hybrid or off-grid solution, depending on your backup needs and grid reliability.
“How reliable is your current power supply?”
- Frequent Outages: For frequent outages, we recommend hybrid or fully off-grid systems.
- Reliable Power: If grid reliability is high, an AC Coupled battery is sufficient, but you will save money in the long run installing a hybrid system.
“How much power do you need during an outage?”
- Minimal Needs (e.g., lights, fridge): AC Coupled battery or single hybrid battery.
- Extended Needs (e.g., HVAC, appliances): Multiple batteries in a hybrid or off-grid setup.
Battery Solutions Based on Need
- Battery-Only Solution:
- Best suited for customers without solar who are primarily interested in backup power for short outages.
- Product Recommendation: FranklinWH Battery with aGate X.
- Hybrid Solar-Battery System:
- Ideal for customers with solar or those planning to install it who want to reduce energy bills, have backup power, and maintain some grid reliance.
- Product Recommendations: Enphase 5P with IQ System Controller
- Off-Grid Solar-Battery System: SolArk Inverter with Discover Batteries
- For customers seeking full grid independence or those in areas with unreliable grid service. This setup supports high energy demands and extensive backup capabilities.
